SPECIFICATION forming part of Letters Patent N0. 793,021, dated June 20, 1905.

Application tiled February 4,1905. Serial No, 244,632.

lo HN Ich/)111, it m/r/,y/ concern:

Be it known that I, Ivan A. OLsnN, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in lVall Linings, of which the following' is a full, clear, and exact description, reference being had to the accompanying (.lrawings, which Vform a part of this specification.

My invention relates to the construction of wooden buildings; and it consists in providing portable wall-lining through the use of which dead-air spaces my be provided between the timbers constituting' the frame, (the studding, lioists, and rafters,) thereby rendering the walls, floors` and roof impervious to the air.

To this end my invention consists in so fashioning a cellular wall-lining as to make of it a transportable article of manufacture.

In the drawings referred to, Figure I is a horizontal section of a wall furnished with my cellular wall-lining; Fig. 2, a vertical section of a floor Vfurnished therewith; Fig. 3, a perspective of a portion of my lining cut `from a strip; Fig. l, an end view of my cellular wallliningl folded, and Fig. 5 a roll or bundle of my cellular wall-lining as when ready for shipment.

Similar letters refer to similar parts throughout the several views, A being' my cellular wall-lining, Il the studding to which it is affixed in a wall, and (j the joist to which it is allixed, as in a floor.

My wall-lining A consists of two or more strips of paper, cloth, or other fibrous material of unequal widths, stitched, cemented, or otherwise united at their longitudinal edges, as shown by dotted lines d, as shown in Fig. 3, said strips being respectivelyY creased intermediate their width, (preferably midway between their opposite edges,) as shown by creases /f in Fig. l, the narrower strip c being of sufficient length to reach Yfrom one piece of joist to another, from one piece of studding to another, or from one rafter to another, exclusive of the united edges lying outside the dotted lines u, (at which the lining is laterally bent when securing' it in place.)

follows: The Aframe of the building having been erected, the floor-boards nailed to the joists, the sheeting nailed tothe studding, and the roof-boards nailed to the raftersI measure the distances lying between the oppositely-faced sills when for floors, between the plates and the sills when for walls, between the ridgepole and the plates when for roofs, and cut my lining to lit into these several compartments. These strips l respectively insert between the joists, studs, or rafters and se secure them in place as follows: 'laking a strip of my lining l bend one of the longitudinal edges thereof along the dotted line rl. lay the laterally-bent portion thereofagainst the side of one joist, stud, or rafter, (as the case may bc,) lay a cleat l thereon, (straps of lath may be substituted for cleats as long as the liningstrips.,) and drive the nails e through the cleats, through the united and bent portion of the lining, and into the timber, thus securing it in place at one edge. l then extend the lining across the intervening space to the oppositcly-faced timber, (the joist, stud, or rafter, as the case may be,) to which I secure it in like manner by means of other cleats d and other nails c, as shown in Figs. l and 2.

It will be seen that as the narrower strip of papel' c, constituting' one leaf of the bifolds of my wall-lining, is adapted to extend from one ioist to joSt, from stud to stud, or from rafter to rafter, that the wider strip of paper f, constituting the other leaf of the bifold,

must needs be deflected and lay separate and apart Vfrom the lil'stfnanied leaf c, and it is through having these strips of paper of unequal widths that the wider rcccdes from the narrower and that the dead-air spaces between them are formed.

lVhat I claim as new, and desire to secure by Letters Patent, isn4 1. As a new articlel of manufacture, a walllining consisting of multiple folds of paper or other fibrous material of different widths, said Vfolds being united at their longitudinal edges and creased intermediate their length said united edges being' adapted to lateral dellection, and to be secured to oppositcly-faced timbers, in the manner, and for the purposes .l atlix my cellular' wall-lining in place as i herein shown and described.

IOO

2. As a new article of manufacture, a Walllining fashioned of multiple strips oit' unequal width, said strips being united at their parallel longitudinal edges, and creased intermediate their Width, thereby providing dead-air spaces intermediate the said strips, through the unequal deiiection of the respective strips, substantially as shown and described.

3. As a new article of manufacture a bifold of paper, cloth, or other fibrous material the leaves of which are of unequal width having' the parallel longitudinal edges of the two leaves united; and each being creased intermediate its width, thereby providing for unequal deiiection of its leaves, and for an intermediate dead-air chamber, substantially as shown, and for the purposes specilied.
